Materials

 * 1) 22 gauge copper wire
 * 2) Double sided tape
 * 3) One large nail
 * 4) One small nail
 * 5) One 9 volt battery

Preparing the Core
Before wrapping the wire around the core, the core must be wrapped in the double sided tape. So start by wrapping the nail in two small pieces of the double sided tape.

Wrapping the Wire
Once the core is wrapped with the double sided tape, it is ready to be wrapped with the 22 gauge copper wire. When wrapping the wire, make sure that the coils are as close together as possible. This will increase the strength of the magnet. Also, leave extra wire at the ends of the magnet so that it can be connected to the battery.

Testing the Magnet
After the magnet has been wrapped in the wire, attach the two ends of the wire to the (+) and (-) ends of the battery, and then touch the core of the magnet (the large nail) to the smaller nail and see if it picks it up. If it does not, the battery may be dead, or the electromagnet requires more coils. --MikeBertrand6 (discuss • contribs) 16:46, 14 March 2013 (UTC)
